Thanks all!
I will have to take some more pics. I am not in the habit of shooting the equipment, sorry about that. I typically don't care much about that stuff because we all seem to know what works these days, and our systems are nothing special-- just straightforward solid systems that cover the basics-- good flow, skimmer, chiller, refugium. But Doug can tell you more.
Doug Petranoff is in charge of the care of this aquarium and will chime in shortly with the technical details/parameters etc., with which he is very well versed.
